Oculi are important collectibles that can be found all over Teyvat. These can be used to Worship the Statue of The Seven, which will, in turn, grant you various rewards. You'll find most oculi floating in the air—but some are hidden behind puzzles.
In the Kujou Encampment, you'll encounter an Electroculus stuck underneath a locked gate, further blocked by two Thunder Barriers. Solve the nearby Relay Stone puzzle to unlock it.
Start by heading to the location circled in the image above. Jump down, and you'll find a locked gate and a Relay Stone puzzle. Beside a bush behind the puzzle, you'll find the first Relay Stone. The second is located near a bush on the elevated landform in front of the puzzle.

Pick up the Relay Stones and position them as prescribed in the image above. On the right, the Stone should be behind the bush between Discharge Stone on the right and the Cumulation Stone in the middle. If the Electro Current doesn't form, make micro-adjustments to your position until they connect.
Likewise, place the second Relay Stone between the two Stones on the left. It should be closer to the Discharge Stone on the left and a bit further away from the middle. If the lines don't connect, adjust your position again until they do.
If you don't complete this puzzle, it will reset after teleporting away or relogging. If you do complete it, the locked gate will open, revealing an entrance that leads to the area underneath. You can acquire an Exquisite Chest and pick up an Electroculus inside.
